Yesterday whilst walking the dog on Peek Hill I found this letterbox out in the open.

It was a single pillpot (with no marks carved in it) containing a foam stamp depicting two flying skeletons and the words "Carnaval de Muerte". No book. I took it home as I have no idea where it should go, but I go there quite often so I could place it somewhere (or get it to its owner). So if anyone knows anything about this box then let me know.
